<DIV>I use Mpich2 to run Quantum Epresso code. I have a error when I try to run execute file pw.x.</DIV>

<DIV>In the output file, the error is: </DIV>

<DIV> </DIV>
<DIV>I tried to test mpiexec command whith some another execute file and there was no problem. The pw.x is also ok when it was run alone (serial running). </DIV>
<DIV> </DIV>
<DIV>Please give me some suggestion for this error. I also saw this problem in PW_forum but I can find the solution for it.</DIV>
